Abstract
A brake transmission shift interlock actuator includes a bobbin that has an open end and a closed end. A plunger is slidably disposed within the bobbin and a plunger rod extends from the plunger. Moreover, a primary plate is installed within the open end of the bobbin. The plunger is movable between an unlocked position, wherein the plunger rod does not extend through the primary plate and a locked position, wherein a first end of the plunger rod extends through a bore formed by the primary plate. Further, a magnetic force of attraction between the plunger and the primary plate diminishes as the plunger approaches the primary plate.
